  • FIG. 7 is a section taken along the line VII--VII of FIG. 6.
  • FIG. 8 diagrammatically shows an arrangement which will bring about the movements of the cylinder-piston systems will with all hydraulic power systems be effected uniformly.
  • FIG. 9 illustrates the supply of pressure fluid required for driving the wheels.
  • FIG. 10 illustrates a modification, according to which the rubber tire equipped wheels on the transverse sides of the understructure instead of or in addition to wheels can be provided on the longitudinal sides of the understructure.
  • FIG. 10a shows the wheels pivoted on the transverse sides and arranged on parallel lines.
  • FIG. 10b shows the wheels pivoted on the transverse sides and arranged on concentric circles.
  • FIG. 11 shows an arrangement according to which the wheels are so pivoted that a so-called dog-walk (hundegang) is effected with which all wheels being parallel to each other are positioned at an angle with regard to the longitudinal axis of the understructure.
  • the understructure 1 has a U-shaped contour and on the charging side is provided with a foot portion 2 which extends over the width of the understructure.
  • the understructure 1 is provided with two foot portions 3.
  • two pairs of wheels 4 with rubber tires Arranged on each of the two sides of the understructure 1 are two pairs of wheels 4 with rubber tires. These wheels are vertically displaceably guided on the understructure 1.
  • the lifting and lowering of the wheels 4 relative to the understructure 1 or of the understructure relative to the wheels is effected by means of double acting hydraulic power operable devices the cylinders 5 of which rest on the understructure 1 while the connecting rods 5a pertaining to said cylinders 5 rest on the axle supports 6 of the wheels 4 (FIGS. 3 and 4).
  • Some or all rubber tire equipped wheels 4 are equipped with hydraulic individual drives and transmissions.
  • the wheels 4 are pivotable in the manner illustrated in FIG. 5. In certain circumstances it will suffice if only some of the wheels are pivotable for steering purposes.
  • FIGS. 6 to 8 An arrangement which is the reverse of the above described embodiment is shown in FIGS. 6 to 8.
  • one of the cylinders 5 of the hydraulic power devices is slidably guided along a vertical wall 20 of an extension 21 of the understructure 1. This is effected by mens of jaw-shaped strips 22 (FIG. 7) which extend around the wheels which protrude in a flange-like manner and are arranged at the wall 20.
  • the connecting rod 23 of the piston guided in cylinder 5 extends through a stuffing box in the upper end face wall of the cylinder and has its upper end connected to a bracket of the extension 21.
  • Cylinder 5 continues downwardly in a frame 25 within which by means of an upper and lower ball turntable 26, 27 respectively there is journalled the hollow shaft 28 of one of the wheels 7 for pivotal movement about a vertical axis 29.
  • the pivoting of wheel 4 is effected by means of a hydraulic power operable device the cylinder 30 of which is pivotally connected to the understructure 1 while its connecting rod is pivotally connected to a lever 31 on frame 25.
  • a hydraulic driving motor 32 and a transmission 33 which conveys the driving energy to the wheel 4 which in turn by means of ball bearings 34 is journalled on shaft 28.
  • conduits 35, 36 for feeding and withdrawing liquid.
  • Conduits 37, 38 are connected to the upper and lower end of the cylinder 5 for feeding and withdrawing liquid.
  • the cylinder 5 is lifted to the illustrated position by means of pressure fluid which is inroduced into the cylinder chamber above piston 24 through conduit 37 while liquid from the lower cylinder chamber passes through conduit 38.
  • the wheel 4 is lifted off the ground while the lower structure 1 by means of its legs 2, 3 rests on the ground.
  • FIG. 5 illustrates that all wheels 4 are pivotable for steering purposes. Under some circumstances it will suffice that only some of the wheels are pivotable for steering purposes.
  • the charging belt conveyor is designated with the reference numeral 9 and the discharging belt conveyor is designated with the reference numeral 10.
  • Adjacent thereto and provided on the understructure 1 is a funnel 11 for transferring the material to be crushed onto a conveyor belt 12 which is pivotable about a vertical axis.
  • the pressure fluid for the hydraulic power operable devices 5 is furnished by a pump unit 13 which is mounted on the understructure 1.
  • the wheels 4 are in pairs combined to hydraulic units inasmuch as the cylinder 5 of each two hydraulic power operable devices are interconnected through equalizing conduits 14 through the connecting conduits 37, 38 (FIG. 6).
  • the conduits 14 of two wheel pairs 4 arranged on opposite sides of the understructure are interconnected by equalizing conduits 15 connected through conduit 50a to conduit 50, which connects to pump unit 13.
  • Equalizing conduits 14 for the other two wheel pairs are connected to conduit 50 by separate conduits 50b and 50c, respectively.
  • a control device is connected in each of the conduits 50a, 50b and 50c to control hydraulic devices 5 (See FIG. 6).
  • FIG. 8 illustrates an exemplary embodiment therefor.
  • three pumps 40, 41 and 42 are provided, and each of these pumps is by means of a pressure fluid conveying conduit 43, 44, and 45 respectively connected to an equalizing conduit 46, 47 and 48 respectively through which the cylinders 5 of four groups are connected to each other to form the three supporting points I, II and III.
  • the pumps 40, 41 and 42 have a common drive comprising a motor 49 so that they will automatically deliver equal quantities of liquid per time unit.
  • FIG. 9 further illustrates that the pump unit 13 furnishes the pressure fluid required for driving the wheels 4.
  • the conduit 50 originates at the pump unit 13 which conduit 50 has connected thereto the equalizing conduits 14 (FIG. 5), but at the pump unit 13 additionally originate two conduits 51, 52 from which branch off the connecting conduits 35 for the driving motors 32.
  • a pressure fluid conveying conduit 53 leads from the pump unit 13 to a hydraulic motor 16 by means of which the reversing drum 54 of the discharging belt 10 may be driven. This is effected when during the crushing operation neither the cylinders 5 nor the motors 32 require pressure fluid. In such an instance, also the crusher 8 can receive its driving energy from the pump unit 13.
  • a conduit 56 leads from the pump unit 13 to a hydraulic motor 67 for delivering pressure fluid for the drive of the crusher 8.
  • Each of the pressure fluid conveying conduits 43, 44, 45, 50-53, 56 has associated therewith a return conduit.
  • FIG. 6 shows that the conduits 50 and 51 have associated therewith parallel return conduits 57 and 58 respectively which end above a fluid collecting container 59.
  • the control device or two-way valve 60 Interposed between the conduits 50 and 57 is the control device or two-way valve 60 by means of which, as illustrated, an equalizing conduit 14 pertaining to the conduit 37 is connected to the conduit 50, and an equalizing conduit 14 pertaining to the conduit 38 is connected to the conduit 57.
  • A corresponds the lifting of the cylinder 5.
  • the rubber equipped tires in addition to placing them on the longitudinal sides of the understructure or instead thereof, on the transverse sides of the understructure as shown in FIG. 10 and may be pivoted individually as in FIG. 10a. If necessary, the rubber equipped wheels may also be so pivoted that a so-called "dog walk” is realized at which all wheels extend at an incline with regard to the longitudinal axis of the understructure and parallel to each other as shown in FIG. 11 or may be positioned on concentric circles as in FIG. 10b.
  • the invention brings about the advantage that on one hand the crushing implement can in a minimum of time and in a considerably shorter time than was heretofore possible with crushing implements equipped with stepping machanisms or track-laying means change its place of operation even over considerable distances. Furthermore with a crushing implement according to the present invention, the shocks and vibrations occurring during the crushing operation will not affect the rubber tire equipped wheels nor the hydraulic power operable devices.
